上市公司每月營運情形之公告，可讓投資人瞭解各該公司經由營業活動所產生現金流量的多寡、風險與不確定性。若所傳遞之訊息對股價影響愈多，則該公告愈具有資訊內涵。 　　本研究採用事件研究法，來探討台灣證券交易市場民國80年至民國83年間，112家樣本公司的3896個每月營運情形公告樣本的資訊內涵。本研究以市場模式、複迴歸摸式來衡量上市公司每月營運情形公告傳避至證券交易市場的資訊有用性與價值。依本研究之研究方法與實證分析，依序獲得下列各項結論： 　　1. 公告時間之早晚與未預期每股營收之正負有關。亦即，當未預期每股營收為正時，上市公司會於每月十日以前提早公告此項好消息；而當未預期每股營收為負時，則會拖延至每月十日以後才公告此項壞消息。 　　2. 未預期每股營收為正時，除中間組之樣本群於相對日數第-7日至第2日間具有資訊內涵外，均不具有資訊內涵。因此，整體而言，該資訊的市場反應與預期的不符，經細分後，對資訊的解釋亦無多大的幫助。 　　3. 未預期每股營收為負時，除了全部樣本群之相對日數第1日、最小組樣本群之相對日數第-3日至第7日、中間組樣本群之相對日數第-7日、與最大組樣本群之相對日數第-6、-4、-3日以外，均具有資訊內涵。因此，整體而言，該資訊的市場反應大部份與預期的相符。然而細分之後，各組的市場反應並未符合預期的趨勢，因此，資科的細分對資訊的解釋並無多大的幫助。 　　4. 未預期每股營收與未預期每股營收成長率，對累積平均異常報酬率而言，均不具有統計上的顯著影響力。 　　5. 對整體股市而言，上市公司每月營運情形之公告，於開窗期間為相對日數第-7日至第7日之複迴歸模式一、與開窗期間為相對日數第1日至第7日之複迴歸模式三，均具有資訊內涵。

本研究主要目的在探討證券管理委員會所強制編製之財務預測報告是否具有資訊內涵。在美國，證券交易委員會對財務預測資訊之揭露，係採鼓勵但不強制的態度。財務預測資訊由市場供需所產生，且有司法體系監督著，對於散佈不實消息包括財務預測，影響市場運作者都會受到應當懲處。故其財務預測資訊相對而言準確性較高。反觀我國預測制度，證管會基於保護投資人的立場，達到資訊充分公開，強制公開財務預測資訊。但在目前的規範體系下，後續監督能力可能較弱，市場機制未能充分發揮，是以強制公開並不能保証其合理性。 　　依據「證券發行人財務報告編製準則」第15條，及「發行人募集與發行有價證券處理準則上第18條、第25條規定，上市公司如有現金增資或公開發行公司申請上市、募集與發行可轉換公司債時，需強制性揭露財務預測，上市公司亦可自願性地揭露財務預測。當編製財務預測所依據之關鍵因素或基本假設發生變動，致營業毛利（修正前為營業損益）或稅前損益變動達百分之二十以上（修正前為百分之十以上），且影響金額達一千萬以上，公司需更新及申告公告財務預測。 　　在財務預測相關規定下，根據資訊不對稱經濟學(Economics of Informational Asymmetry)，本研究以為資訊提供者會評估其相關成本效益來決定資訊品質。由於國內相關法規對劣質財務預測資訊並無足夠罰則，且資訊環境的效率性存疑，因此，本研究大膽假設國內財務預測資訊不存在資訊內涵。另外，根據國外實證研究，公司會傾向提早公佈好消息，延遲壞消息之公佈。本研究另一實證研究，係探討財務預測更新資訊型態與公告時間性之關連性。 　　實證結果彙總如下： 　　1.我國財務預測（原始預測）之公告不具資訊內涵。 　　2.財務預測更新資訊為正向更新者，不具資訊內涵。但若財務預測為負向更新之資訊揭露，在事件期會產生負的異常報酬。此實證結果意味著，負向財務預測更新代表公司原始預測過份樂觀，亦可能公司預計營運能力的衰退。所以，市場會有負向的反應。 　　3.時間性實證研究結果顯示，公司會延遲公告負向財務預測更新。

A fast simulated annealing algorithm is developed for automatic object recognition. The normalized correlation coefficient is used as a measure of the match between a hypothesized object and an image. Templates are generated on-line during the search by transforming model images. Simulated annealing reduces the search time by orders of magnitude with respect to an exhaustive search. The algorithm is applied to the problem of how landmarks, for example, traffic signs, can be recognized by an autonomous vehicle or a navigating robot. The algorithm works well in noisy, real-world images of complicated scenes for model images with high information content.

Manufacturing globalization and sustainable development compel production enterprises to continuously seek improvements in their products performance, customization, environmental friendliness, cost, and delivery time. The challenges of this competition cannot be completely addressed through improving production processes because some issues can only be solved through more innovative design. This thesis investigates a new design paradigm called Design for Adaptability or Adaptable Design (AD) to address some of these challenges. The purpose of AD is to extend the utility of designs and products. An adaptable design allows manufacturers to quickly develop new and upgraded models or customized products through adapting existing designs with proven quality and costs. An adaptable product can be utilized under varying service requirements thus prevents premature product replacement. Design adaptability and product adaptability provide economical and environmental benefits of AD. <p> To make a product adaptable, its adaptability must be built-in during the design stage. Methods of design for predetermined adaptations are categorized as Specific AD; these methods design products for versatility, upgrading, variety, and customization. Several of these methods such as modular/platform design and design for upgrading have been studied for mechanical design. In the absence of predetermined adaptations, AD aims to increase the general adaptability of products. General AD involves fundamental research in design theory and methodology in order to develop practical design methods and guidelines. This thesis introduces several original concepts and proposes the subordination of a system to a rational functional structure as an approach for increasing general adaptability. Such a system would consist of a hierarchical assembly of autonomous functional modules, emulating the adaptable architecture of a rational functional structure. Methods and guidelines are proposed for making the design of mechanical systems closer to this ideal architecture. <p> Accordingly, the thesis proposes a methodology for AD in which specific AD is performed first to take advantage of available forecast information, and then general AD is performed in order to increase adaptability to unforeseen changes. Also, a measure has been defined for the assessment of adaptability. The application of this methodology has been demonstrated through several conceptual design examples.

The study aims to detect the influence of the initial cross-listing of Taiwanese enterprises on the variety of the stock price of the listing company and its rival firms. However, the limitations from the Taiwanese authorities on the local company¡¦s direct listing in the oversea market are not a few. Accordingly, I employ GDR instead of direct international listing to delve the phenomenon of information content and intra-industry transfer derived from a company¡¦s initial GDR offering. Recent studies focusing on the same issue rarely inspect the situation of Taiwanese industries. Thus, the research intends to excavate the effect and the aftermath of a Taiwanese firm¡¦s initial GDR offering on its local market price as well as on the one of its rival company that concurrently does not have GDR offering. To delineate the complication of the issue, the study develop three trajectories mainly based on various approaches, including reference review, event study method, and multi-regression analysis. The first aspect attends to the research result of event study method and multi-regression analysis that exposes the stock price of the GDR offering company has abnormally positive rise accompanying with the announcement of its GDR offerings, particularly in the period before the announcement. That reflects the investors regard the GDR offering as a positive news for a company while the situation turns out to be the opposite for the rival firms. The research also finds that industry differences might dominate the consequence of the GDR offering. Hence, the exemplary simples are divided into the ¡§hi-tech¡¨ industry group and the ¡§non hi-tech¡¨ industry group. Based on the reference review of Melvin and Valero-Tonone¡]2005¡^ and the outcome of the multi-regression analysis, the influence of GDR offering on both industry group will be carefully scrutinized. In addition, the study places another attention on the discussion of intra-industry transferring and the contagion effect of the GDR offering on the offering company and its rival firm. Although Taiwanese enterprises offer GDR mainly in four main trade locations from London, Luxembourg, New York, and NASDAQ, the study exposes that the trade location has less influence on a company¡¦s and its rival firm¡¦s SCAR variation. That implies that Taiwanese investors might recognize the fact of a company¡¦s GDR offering in the oversea market, whereas, they seldom be aware of the trivial differentiation of the disparate trade location. In conclusion, the GDR offering of Taiwanese enterprises indeed encompasses information content that might motivate the alteration of the stock price in Taiwan stock market. Besides, the action of GDR offering supplies intra-industry information transferring effect. Even though the strategy of offering GDR of a Taiwanese company does not rely on consulting the action of its rival firms, in reality and according to the application of game theory, the implementing efficiency of a company¡¦s strategies might probably be impinged by its opponents¡¦ behavior. In other words, while a company offers GDR, its rival firms should propose expedients to reduce the damage that might be caused by the issue information.

Two essays are comprised in this dissertation to explore how market friction affects the processes of price formation. The first essay investigates on both theoretical and empirical bases how segmentation of communication amongst potential lenders can influence loan contracts. Two cases are considered. The first one assumes that potential lenders can freely communicate with each other; the second one assumes that each potential lender can only observe the decisions of its predecessors. I show theoretically that the ex post observed interest rate will be higher and the probability of syndication failure will be lower if the potential lenders cannot communicate freely with each other. These predictions are confirmed by my empirical work. Using a novel proxy, relational distance, for the segmentation of communication, I show that the larger the relational distance, the higher is the loan spread and the lower is the probability of syndication failure. In addition, the relational distance is positively correlated with the probability of the existence of non-price contract terms, such as the requirement for collateral and guarantees. My conclusions are found to be robust to endogeneity issues, potentially omitted variables and alternative model specifications. The second essay focuses on the informational effects between futures market and its spot market. Intraday data are used to investigate the lead-lag relationship between the TX returns, the TX trading activity and the TAIEX stock index returns. I focus on the transmission direction and the source of information and find that there are specific lead-lag relationships between futures returns and spot returns, in addition to the contemporaneous relationship predicted by carry-cost theory and efficient market theory. The results show that futures returns significantly lead spot returns, which suggests that informed trades occur in the futures market and makes information flows from the futures market to the spot market. By distinguishing different types of futures traders and using private information, net open buy, as a proxy for futures trading activity, I found that the major source of informed trades is foreign institutional traders because their trading activity have predictive power for future movements in both spot and futures prices. In contrary, traders in the other categories carry no information about the directional changes in both spot and futures prices.

本研究探討Banker and Chen (2006)建構之CVCS模型與本研究建構之CVCS’模型之盈餘預測準確度與資訊內涵，並以ROE模型、OPINC模型、CASHFLOW模型與分析師盈餘預測作為判斷CVCS模型與CVCS’模型是否具有盈餘預測準確度與資訊內涵之比較基準模型。盈餘預測準確度之實證結果顯示：(1)CVCS模型之盈餘預測準確度低於ROE模型、OPINC模型與CASHFLOW模型之盈餘預測準確度；(2)CVCS’模型與ROE模型、OPINC模型、CASHFLOW模型之盈餘預測準確度並無差異；(3)CVCS模型之盈餘預測準確度低於分析師盈餘預測之盈餘預測準確度；(4)CVCS’模型之盈餘預測準確度低於分析師盈餘預測之盈餘預測準確度。資訊內涵之實證結果顯示：(1)CVCS模型之資訊內涵高於ROE模型、OPINC模型與CASHFLOW模型之資訊內涵；(2)CVCS’模型之資訊內涵低於ROE模型、OPINC模型與CASHFLOW模型之資訊內涵；(3)CVCS模型之資訊內涵低於分析師盈餘預測之資訊內涵；(4)CVCS’模型之資訊內涵低於分析師盈餘預測之資訊內涵。 / This study examines the forecast accuracy and the information content of CVCS model, proposed by Banker and Chen (2006), and CVCS’ model, constructed by this study. To evaluate the performances of these two models, this study uses ROE model, OPINC model, CASHFLOW model and analysts’ consensus forecasts as the benchmarks. The results of forecast accuracy show (1) the forecast accuracy of CVCS model is less than that of ROE model, OPINC model, and CASHFLOW model, (2) the forecast accuracy of CVCS’ model is not different from that of ROE model, OPINC model, and CASHFLOW model, (3) the forecast accuracy of CVCS model is less than that of analysts’ consensus forecasts and (4) the forecast accuracy of CVCS’ model is less than that of analysts’ consensus forecasts. The results of information content show (1) the information content of CVCS model is greater than that of ROE model, OPINC model, and CASHFLOW model, (2) the information content of CVCS’ model is less than that of ROE model, OPINC model, and CASHFLOW model, (3) the information content of CVCS model is less than that of analysts consensus forecasts, (4) the information content of CVCS’ model is less than that of analysts consensus forecasts.

美國存託憑證(American Deposit Receipt，ADR)對美國投資人而言是進入外國市場最簡便的方式之一，因為它以美金計價且在美國交易。發行ADR可以使公司的知名度提高，增加股票的流動性，進而提高股票價格。 有些國家對外資設有投資上限，使外資投資不易或投資成本太高，造成投資障礙。透過購買美國存託憑證可以持有表彰外國公司股份的股權，為投資人帶來收益且達到風險分散效果。亞洲地區為發行美國存託憑證最多的地區，本研究選取了九個新興國家以及日本企業所發行的ADR為研究樣本，探討三個問題：美國存託憑證價格的折（溢）價是否有資訊內涵、美國存託憑證的折(溢)價是否受到美國市場情緒影響以及發行ADR後，本國市場的股票訂價效率是否改善。 研究結果發現，多數ADR折（溢）價的資訊內涵為正向且顯著，意即，今日美國存託憑證的折（溢）價透露出隔日標的股票報酬率的訊息。顯示美國存託憑證存在溢價，不只反應外國政府設立的投資障礙或是外國股票的交易成本過高，還透露出對隔日標的股票報酬率的預期。 美國存託憑證雖然表彰的是外國公司的股權，但卻是在美國交易。ADR的價格不只反應出與標的股票本身的價值，可能還受美國市場情緒影響。本研究的實證結果支持ADR價格受到美國市場情緒影響的論點。表示投資人在選擇美國存託憑證投資標的時，除了要對公司進行合理的評價，也要將美國市場的表現納入考慮。 本研究的研究樣本為九個新興國家以及日本，開發中國家可能對外資設有投資限制且市場資訊效率不高，造成股票的訂價未完全反應其真實價值。海外上市後，更多投資人參與交易，市場資訊環境改善，本國市場的股票訂價效率應該因此提升；過去探討海外上市公司的外國市場價格與本國市場價格間共整合過程的文獻，多以一階自我相關為基礎所發展出來的模型進行實證且未除去市場效率改善帶來的影響。使用一階自我相關為基礎的模型時，須假設樣本為常態分配，但股票報酬的分配很可能不符合常態分配，導致實證結果有偏誤；本研究以無母數連檢定(Run Test)進行實證並除去同時期市場效率改善的影響。究實證結果顯示，股票報酬率在海外上市後變得更為隨機，可預測性降低，表示資訊環境改善明顯有助於股票價格反應其真實價值。 / American Deposit Receipt (ADR) is one of the most convenient ways for U.S. - based investors to acquire foreign shares since ADRs are quoted in U.S. dollars and are traded in the U.S. markets. Foreign investors have difficulty in acquiring foreign shares because of investment limit or high transaction cost. ADRs issued by companies from nine emerging countries in Asia and Japan were picked as sample data to verify the information content and U.S. market sentiment issues. The empirical result for information content is significant and positive. ADR premium (discount) today reveals information that the return of the underlying stock tomorrow will be positive (negative). ADRs are foreign shares but are traded in the U.S. markets. ADR price may not only contain its intrinsic value but also U.S. market sentiment. The empirical result supports that argument. The result reminds investors that in addition to appropriate valuation of a company, the reaction of other investors in the same market should be taken into account. Employ a simple non-parametric test and control for contemporaneous marketwide efficiency shifts and the potential contamination from the price effect of cross-listing announcement, the empirical result demonstrated that with improvement of informational environment, stock pricing efficiency was enhanced after cross-listing.

Sammanfattning Examensarbete, Civilekonomprogrammet, Ekonomihögskolan vid Linnéuniversitetet Författare: Hanna Rindhall och Jessica Karlsson Handledare: Ulf Larsson-Olaison Examinator: Karin Jonnergård Titel: ”Ger bolag tillräckligt väl motiverade avvikelseförklaringar?” Bakgrund: Nationella bolagsstyrningskoder har sedan offentliggörandet av Cadbury Code i Storbritannien 1992 spridit sig världen över. Genom att ta itu med agentkonflikter är koderna ett sätt att säkerställa att bolaget sköts på ett för ägarna fördelaktigt sätt. Den svenska koden utgår från självreglering där de reglerade subjekten antingen kan välja att följa kodens rekommendationer eller förklara varför de inte gör det, enligt principen “följ eller förklara”. Det innebär att bolaget kan avvika från enskilda punkter i koden men att en informativ och företagsspecifik förklaring krävs till avvikelsen i bolagets bolagsstyrningsrapport. Syfte: Uppsatsens syfte är att, utifrån ett longitudinellt perspektiv, förklara vad som påverkar informationsinnehållet i bolags förklaringar vid avvikelse från Svensk kod för bolagsstyrning. Metod: Studien har en deduktiv forskningsansats där den teoretiska grunden, som förväntas förklara vad som har en inverkan på förklaringarnas informationsinnehåll, utgår från agentteorin och den institutionella teorin. Den kvantitativa forskningsmetoden bygger på data från bolags årsredovisningar för de studerade åren 2009, 2012 samt 2015. Resultat: Det kan konstateras att bolag i hög utsträckning tenderar att avge kodupprepande och standardiserade förklaringar av lågt informationsvärde och som över tid dessutom inte utvecklas. En underliggande drivkraft till kvaliteten på förklaringarna tycks främst vara styrelsen och dess egenskaper då de egenskaper som identifierats är; styrelsens oberoende, styrelsens storlek, styrelsens ersättning, kvinnliga ledamöter, angloamerikanska ledamöter, Vd i styrelsen samt ägarkoncentration. Utifrån detta kan det vidare konstateras att bolagens förhållningssätt till koden främst kan förklaras i termer av legitimitet. Nyckelord: Svensk kod för bolagsstyrning, Koden, Följ eller förklara, Avvikelse, Informationsinnehåll / Abstract Master Thesis in Business Administration, School of Economics, Linnaeus University Authors: Hanna Rindhall and Jessica Karlsson Supervisor: Ulf Larsson-Olaison Examiner: Karin Jonnergård Title: “Does companies' provide sufficiently well-founded explanations of deviations?” Background: Since the release of the Cadbury Code in the UK in 1992, national corporate governance codes have spread throughout the world. By addressing agent conflicts, the codes are a way of ensuring that the company is managed in an advantageous way for the owners. The Swedish code is based on self-regulation, where the regulated subjects either choose to follow the code's recommendations or explain why they do not, according to the principle "comply or explain". This means that the company may deviate from individual items in the code, but that an informative and company-specific explanation is required for the deviation in the company's corporate governance report. Purpose: The purpose is to explain, from a longitudinal perspective, what influences the information content in companies' explanations in deviation from the Swedish Code of Corporate Governance. Method: The study has a deductive research approach in which the theoretical foundation, which is expected to explain what has an impact on the information content of the declarants, is based on the agency theory and the institutional theory. The quantitative research methodology is based on data from companies' annual reports for those studied in 2009, 2012 and 2015. Conclusions: It can be noted that companies tend to provide coding repetitive and standard explanations of low information value that, over time, do not develop. An underlying driving force for the quality of the explanations appears primarily to be the board and its characteristics when the characteristics identified are; board independence, board size, board remuneration, female directors, anglo-american directors, CEO of the board and concentration of ownership. Based on this, it can be further stated that the company's approach to the code can be explained primarily in terms of legitimacy.
